SPECTACLES.

Patented sept. 17, 1912.

Application led July 15, 1911. Serial No. 638,623.

` LThe essential objects of my invention are to provide a maximum capacity adjustment both as regard to focal position of the lenses and to the physical characteristics of the wearer; to -insu're in a single type of com-V bined bridge and guard a universal adjusti ment, that is to say adjustment in a horizontal plane toward and away from and beyond the plane of the lenses, adjustment in a 'vertical plane, adjust-ment right and left in the plane of thelenses, and adjustment of the angle of vertical convergence of the crest of the bridge.

Other objects are facility of adjustment,

and simplicity and inexpensiveness of construction. j

- Figure l is4 a rear view of a pair of spec= tacles embodying my invention, with portions of the temples broken away. Fig. 2 a top plan view of the same, Figs. 3, 4, and 5, sections of the same on line .fnof Fig. 1, showing the bridge in adjusted positions of out, om and h in, respectively. Fig.

-(3, a like section of the same corresponding with Fig. 4 and showing in broken lines a downward adjustment of the bridge, Fig. 7, a .rear view of the spectacles lwith parts broken away and showingj` in broken lines positions of adjustment for varying pupilary distances. Fig. 8, a plan view of the ,.same, and Fig. 9, a similar view of'a modi-v lied form of bridge portion. i

Like characters of reference indicate like parts -throughout the views.

In the drawings, A, indicates 'the supports, and, a, the lenses of a pair of spectacles of the rim type in conjunction with which my invention is used. My invention is also applicable to the rimless type. `The temples B may be of any usual desired construction. j

The bridging portion C is com osed of pliable or flexible material, and 1ndetail comprises .a crest or arched portion, o, inclined rearwardly and downwardly forming arms, d, which have an angular bend, e,

the lenses.

and forwardly forming shank portions, f, each provided with a bend,g, and extending horizontally forward and slightly outwardly forming horizontal portions, h, integral with or soldered to the lens supports A at points below the horizontal axes of The construction of the bridge portion C is such that combined withthe pliable material' thereof the portions d, e, f,

vmay be made to conform to the sides of thel nose and form in eect an extended side bearing whereby the weight may be taken from the crest, c, and the usual abrasion of ,the nose below the crest of the bridge be thus avoided.4

Without impairing the engagement of the bridge portions c, d, e, and' f to the sides of .the nose, these parts are capable of being swung to various positions transversely of the planes of the lenses', by bending the portions a, or opening the bend g. Adjustment to the three most necessary positions of out on, and in are shown respec- In out posif .tion the crest c is in fro-nt of the plane of the frames; in on position, in the plane of the frames; and in inv position, at the 'rear of the plane.

.Without lessening the grip of the portions al, c, f, of the bridge portion, the latter is capable of vertical adjustment. This is illustrated in broken lines in Fig. 6 which indicate a lower position of the crest by depressing the arms, d, at the bend c.

Adjustment of the lens supports toward and away from each other as is desirable in adjustment for pupilary-distance may also be attained by manipulation of the bridge portion alone wit-hout destroying conformation of the latter to the sides of the nose. This is attained by bending outwardly the portions h, g', and the lower parts of the portions f, as illustrated inFigs. 7 and 8.

It is sometimes convenient to employ the modified form of my invention shown in Figg9 which includes supplemental supports J connected by arms I integral with or soldered to the shank portions, f, o1" the bridge. These auxiliary nose supports are and extend at an inclination downwardlyl also of pliable material and are capable of 1. In spectacles, the combination with the lens supports, of an arched portion comprising inclined arms provided with bends connected with the lens supports, and auxiliary support-s rigidly connected with the arms.

Q. In spectacles, the combination with the lens` supports, of an arched portionv comprising Arearwardly directed arms provided with angular bends connected with the lens supports, and auxiliary supports rigidly connected to the arms.

3. In spectacles, the combination with the lens supports, of anarch'ed portion comprising rearwardly and downwardly inclined arms provided with angular bends and continued forwardly from the said bends to L form shanks connected with the lens supports, and auxiliary supports connected with the Shanks.

4. In spectacles, the combination with the lens supports, of an arched portion comprising rearwardly and downwardly inclined arms provided with angular bends and continued downwardly and forwardly from said bends to form Shanks connected with the lenssupports, auxiliary supports, and arms connecting the auxiliary supports to the Shanks.

5. In spectacles, the combination with vthe lens supports and lenses, of an arched portion comprising rearwardly inclined arms provided with bends,y downwardly and forwardly inclined Shanks integral with the ports.

lens supports at points below the `horizontal axes of the lens supports, auxiliary supports, and arms connecting the auxiliary supports to the Shanks.

6'. In spectacles, the combination with the lens supports, of an arched portion comprising rearwardly inclined arms continued at an inclination forwardly and downwardly to form Shanks, said Shanks being provided with bends and horizontally extended to unite with the lens supports, auxiliary supports, and arms .connecting the auxiliary supports with an intermediate portion of the Shanks. v

7. In spectacles, the combination with the lens support-s, of a combined pliable bridging and guard portion comprising in a single piece an arched portion consisting of .inclined rearwardly directed arms, forwardly and downwardly directed Shanks integral with the arms, horizontal portions integral with the lower endsof the Shanks fixed to the lens supports, auxiliarysupports, and arms connected to the lens sup- In testimony whereof I have aiiixed my signature 1n presence of two witnesses.
